Abstract
The invention relates to a deep-rolling roller head (1) of a deep-rolling tool for the deep rolling of radii or undercuts (22) on the main and stroke journals of crankshafts (21), with a housing (2) in which one or two deep-rolling rollers are tracked with little clearance and are loosely rotatable in a roller cage (5) at a lateral distance from each other. The roller cage (5) is attached to underside (3) of the housing (2) towards the crankshaft (21) by means of pins (15) which support the roller cage (5) on its face (10) away from the deep-rolling rollers (4) and at the same time track them laterally. The housing (2) is provided with a projection (11, 12) for the support of the roller cage (5) on either end of its underside (3) towards the crankshaft (21). Pins (15) serving as fastening and tracking elements of the roller cage (5) are provided and engage the roller cage (5).
